Analyse intersections between spatial DBs — analyse_intersection • floodam.data

The following treatments are performed:

data is adapated consistently with theme
only data corresponding to flood hazards are kept
if scope is given, a subpart of data is also saved

analyse_intersection(
  x,
  y,
  analysis = c("intersect", "proportion"),
  verbose = TRUE
)

analyse_eaip(x, eaip, analysis = "intersect", verbose = TRUE)

Arguments

x: sf object, spatial DB that is analysed.
y: sf object, spatial DB that is used for the analysis.
analysis: character, analyses that is performed. Default to c("intersect", "proportion"). See details.
verbose: logical, should the function gives some messages. Default to* TRUE.
eaip: sf objectf, eaip DB that is used for the analysis.

Value

analyse_intersection returns a data.frame, whose columns contain analyses performed.

analyse_eaip returns a sf object, basically x with added columns for each analysis performed.

Functions

analyse_eaip(): Analyse intersections between spatial DB and eaip DB
